DRY-KILN.

Patented Sept. 24, 19(17.

Application filed October 24, 1906. $erial No. 340,317.

To all whom it may concern:

Be it known that 1, WILLIAM F. HUTCIIINSON, of Nyack, Rockland county, New York, have invented a new and useful Improvement in Dry-Kilns, of which the following is a full, clear, and exact description.

My invention relates to improvements in dry kilns and more particularly to dry kilns such as used for dry ing match splints while they are in holding frames or carriers.

The object of my invention is to produce a simple and inexpensive dry kiln which can be easily set up, which is particularly adapted to dry the match splints, which has means for feeding the frames or carriers holding the splints through the kiln, and which can dry the splints very rapidly.

With this end in view my invention consists of a dry kiln the construction and operation of which will be hereinafter described and the novel features claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the kiln embodying my invention. Fig. 2 is a plan view with parts broken away. Fig. 3 is a longitudinal section of the kiln, and Fig. 4 is a cross section on the line 4. 4 of Fig. 3.

The kiln is provided with a light hollow body portion formed of the side pieces 10 and the top and bottom pieces 11 and 12, the parts being preferably bolted together and they can be conveniently of light castings forming a box-like structure, and while the kiln can be supported in any way, I show it on legs 13 which are connected by cross braces 14. The kiln has openings 15 at the end, wide enough to permit the metal frames or carriers to pass into and out of the kiln. The carrier with which the kiln is generally used, comprises the side frames 16, and the cross rods 17, which connect the side pieces, the splints being held as shown, be tween the cross rods. The side pieces 16 fit in guide tracks 18, which are preferably cast integral with the sides 10 of the kiln but this detail is not essential, and obviously the kiln may be made to receive modifications of the frame.

The match frames are successively drawn through the kilns by means of the cross rods 19, which slide longitudinally in the kiln, and are arranged above and below the track 18 and the match carrier or frame. The slide rods 19 are spaced apart as shown at 20 in Fig. 1, and they can be reciprocated in any convenient way. I show them pivoted as at 21, to the lever 21, and this is fulcrumed as shown at 22, and has its lower end connected to the pitman 23, and the latter has a crank connection as at 24, with a disk 25 on the shaft 26. I have referred to one lever 21 and its connections, but the arrangement is duplicated on each side of the machine. The shaft 26 is mounted in suitable bearings and connected by gears 27 and 28 with a driving shaft 29 and the latter can be turned in any suitable manner. It will be noticed that the turning of the shafts 29 or 26 causes the tilting of the levers 21 and this imparts a reciprocating motion to the rods 19 which connect with the cross rods 1'7 of the carrier frame by means of the opposed pawls 30, which are arranged above and below the frame 16. 17, and engage the cross rods of the frame. A second set of pawls 30 is pivoted on the sides of the kiln and these pawls engage the rods 1'7 and serve as detents. As the match frames or carriers are pushed through the kiln, they are subjected to heat, and this is supplied by a coil of steam pipes 31, in the bottom of the kiln. Obviously these coils can be arranged in any convenient way, and as many pipes may be used as is necessary.

It will be seen that the kiln can be made of any necessary length, as it is longer than would appear by reference to the drawing (see Fig. 19) but the principle is just the same, even though the kiln be made much longer.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent In combination, a box-like structure having an opening to receive a frame, tracks carried by the interior of the structure on which the carrier is movable, reciprocating rods arranged adjacent the edges of the frame and on both side thereof, pawls carried by the rods and clamping the frame, pawls carried by the structure engaging the opposite sides of the frame, and a heating medium within the box-like structure beneath the frame.
